工具准备
No ESD wrist strap is provided with the power module. Prepare it yourself.
安装和拆卸电源模块和电源线过程中需要佩戴防静电腕带，请用户自行准备。
Installing and removing a power module
电源模块的安装与拆卸
①
Put on the ESD wrist strap, and make sure the strap makes good skin contact and is reliably grounded.
佩戴防静电腕带，请确保防静电腕带与皮肤良好接触，并确认防静电腕带已经良好接地。
②
Remove the filler panel, if any, from the target power module slot. Keep the removed filler panel secure
for future use.
若准备安装电源模块的电源槽位上有电源假面板，则在安装电源模块前请先拆卸电源假面板。请善保管
电源模块插槽的假面板，以备将来需要时使用。
③
Unpack the power module and verify that the power module model is as required. Keep the packaging
box and bag secure for future use.
从电源模块包装盒中取出电源模块，确认电源模块的型号与所需一致。请善保管电源模块的包装盒、包
装袋等物品，以备将来需要时使用。
④
Correctly orient the power module. Holding the power module handle with one hand and supporting the
power module bottom with the other, slide the power power module along the guide rails into the slot
until you hear a click.
保证电源模块上下方向正确（电源模块及插槽为防反插结构设计，如果安装方向错误，电源模块将不能
完全插入到插槽中），用一只手握住电源模块上的拉手，另一只手托住电源模块底部，将其后端对准电
源插槽，将电源模块沿电源插槽水平插入插槽。当电源模块完全插入到插槽时，会听到电源模块上的锁
闩卡住插槽的声音。
Installing the power module
安装电源模块
To avoid bodily injury or device damage, follow the steps in the following figure to install the power
module.
电源模块的安装过程应严格按照下图顺序进行，否则可能会对设备造成损坏或对人身造成伤害。
Install the power module
安装电源模块
Connect the power cord
连接电源线
Turn on the circuit breaker
连通电源输入端断路器
Make sure the power module makes good contact with the backplane of the device.
插入电源模块的过程中，可以借助轻微的惯性将其插入插槽，从而保证电源后端与背板插口良好接触。
The power module is foolproof. If the power module is oriented incorrectly, you cannot install the
power module into the slot. To avoid damaging the terminals on the power module, if you
encounter a hard resistance while inserting the power module, pull out the power module, reorient
it, and then insert it again.
为了避免损坏或弯曲电源端子，在插入过程中，如果位置没有对正，请先将电源模块拉出，调整位
置后再重新插入。
The installation and removal procedures for the PSR250-12A and PSR250-12A1 are similar.
This section takes the PSR250-12A for example. PSR250-12A
和
PSR250-
12A1
两款电源模块的安装与拆卸的操作步骤基本相同，本手册以
PSR250-
12A
电源模块为例进行介绍。
Make sure the power module is compatible with the device. For more information about the
compatibility matrix, see the installation guide of the device.
安装前请检查电源模块型号与设备是否匹配，具体请参见各产品的安装指导。
Safety guidelines
安全注意事项
To prevent device damage and bodily injury, follow these restrictions and guidelines when you install
or remove the power module:
为避免对电源模块和设备造成损坏及对人身的伤害，请遵从以下的注意事项：
Before you install a power module, make sure its airflow direction is as required.
在安装电源模块以前，请确认电源模块气流方向和安装环境的通风要求一致。
Do not install power modules that provide different directions of airflow on the same device.
不同风向的电源模块不要混插在同一台设备上。
Always wear an ESD wrist strap and make sure it makes good skin contact.
在安装和拆卸电源模块时，请佩戴防静电腕带，并确保防静电腕带与皮肤良好接触。
Before installing the power module, make sure the voltage of the power supply system is as
required by the power module, and the output voltage of the power module is as required by the
device.
在安装电源模块以前，请确保外置供电系统的工作电压与电源模块所标电压、电源模块输出电压与
设备所需电压一致。
Do not touch any bare cables or terminals of the power module.
请不要接触电源模块中露出的任何导线、端子部分。
Do not place the power module in a wet area, and prevent liquid from flowing into the power
module.
请不要将电源模块放置在潮湿的地方，也不要让液体进入电源模块内部。
To avoid power module damage, do not open the power module. When the internal circuits or
components of the power module fail, contact H3C Support.
为了防止电源模块受损，请不要随意打开电源模块外壳，当电源模块内部线路或元器件出现故障时，
请移交维修人员进行检修。
